F Specification forming part of Letters Patent No. 142,852, dated September 16, 1873; application iiled Iune 21, 1873.

To all Iwhom 'it may concern:

Beit known that we, PAULWILLIAMS and ROBERT A. WrLLrAMs, of Winona, in the county of Montgomery and State ot' Mississippi, have invented a new and Improved CottonPress, of which the following is a specification:

The invention consists of joints in the screws which work the follower, whereby the latter can be swungl away from over the case, to allow of illin g the case with the'cotton or other material to be pressed. Y

Figure l is a-seetional elevation of our iinproved press taken on the line :c of Fig. 2, and Fig. 2 is av sectional elevation'talrenv on theline y y of Fig. 1.

Similar letters of reference. indicate corresponding parts.

A is the upper portion and B the lower por.- tion of the press-oase, which is supported on the head C, which rests, at the center of the press-oase, on the short shaft D, having its' support in a step, E, in any suitable foundation. F is a driving-wheel on the shaft D, gearing with the screws G by the wheels H, and in this example having sweeps I attached for applying the power either'by. hand or aniniais. The frame is supposed to be large enough to allow the animals for applying the power to travel inside of it. A pulley or cogu wheel may be applied t0 the driving-wheel instead ot the sweeps, if it'be desired to apply the power in that way. The screws pass through and have a bearing in the press-head, and also pass through the follower J and the nuts K,'b0lted on .the top, and screw the roilower down and up. L represents the joints oli' from over the top ofthe case, to admit sents, at the part B,.the increasing breadth of the said part of 'the case to 'allow the pressed material to expand a little, and thus relieve the sides from the pressure, so as to prevent bursting. This is more particularly needed for the two sides which constitute the doors for opening to reinove the pressed ball, both because it is difficult to make the' out making them too large, and because the power requiredto release the fastening is lessened.

Having thus described our invention, we "do not claim the combination of jointed screws -with the follower of a press; but

We claim as new and desire to secure by Letters Patent- The combination, with'the box A of the .press projecting above the frame, of the follower J, the screws G, the screw-threaded parts thereof being jointed (below the upper portion A ot the press-box) to the plain-sur- Araced parts thereof, on which are keyed the gears H, as shown and described, for'the purpose specitied.
